On October 26, 2017, President Trump declared the opioid epidemic a public health emergency. Although some commentators have debated its merits, the declaration has already been successful in 1 regard: it has focused national attention on the problem of opioid misuse and abuse. Indeed, the opioid epidemic is a pressing problem. In 2015, opioids were implicated in 33 000 deaths, representing a 4-fold increase since the early 2000s.1 Mortality attributable to opioids is particularly concentrated among younger adults, with an estimated 1 million years of potential life lost annually.2
